I just purchased a 2006 2wd Nissan Titan with 119,000 miles and I love it! I found this forum through google and it is awesome! I was wondering if I could get some input on mods and anything else that would be inexpensive and quick mods. I plan on doing a lot, but wanted to start small and work my way up. I purchased an airaid mxp cai that I will install today and the next mod I wanted to do is the exhaust. I a looking for flow master 40 series dual in dual out. Can anyone recommend the best place to purchase the exhaust and have any input on that particular setup?
